High Performance Extreme Pressure Hypoid Gear Oils
Petronas GL-5 oils are high performance, multipurpose, thermally stable, extreme pressure automotive hypoid gear oils formulated to exceed the severe API GL-5 performance standard.
It is designed and manufactured from selected premium quality base oils and specially selected additives system to provide excellent protection for heavy-duty manual transmission of heavily loaded equipment and passenger vehicles.
Customer Benefits
  • Excellent load carrying ability - the high performance EP additives system provide excellent, long lasting protection against surface stress (scuffing, spaling, pitting, scoring and wear) under the toughest conditions such as heavy dynamic and shock loads.
  • Superior thermal and oxidation stability - the highly refined base oil and special inhibitor system provide excellent resistance toward high temperature oil degradation and oil thickening to ensure deposit do not form around seal and helps maintain clean bearing surfaces to minimize wear.
